DOUBLE-ROW CORN-CUTTER.

Application filed June 4, 1917. Serial No. 172,748.

To all whom it may concern:

Be it known that I, WILLIAM LEE BRIGGS, a citizen of the United States, residing at Gadsden, in the county of Etowah, State of Alabama, have invented a new and useful Double-Row Corn-Cutter; and I do hereby declare the following to be a full, clear, and exact description of the'inventiom such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved d0uble row corn cutter, and one of the objects of the invention is to provide a very simple, efficient and inexpensive and practical device, whereby two rows of corn may becut simultaneously and thrown automatically upon side racks. further object of the invention is to provide improved severing means, whereby, as the machine travels forwardly, two rows of stalks may be cut at the same time.

A further object of the invention is to provide a device of this kind having means, whereby, as the stalks are severed, they are automatically thrown upon side racks.

A further object of the invention is the provision of rockable racks arranged on the sides of the frame of the machine. at the end thereof, to receive the stalks as they are severed or cut, in combination with improved means for rocking the racks downwardly and outwardly, whereby thestalks may be dumped at different intervals across the field. I

In practical fields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The inventioncomprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a plan view of the-improved double row corn'cutter constructed in accordance with the invention,

Fig. 2 is a view in side elevation,

Fig. 3 is a longitudinal sectional view on line 3-3 'of Fig. 1,

' Fig. 4 is a detail perspective View of the corn stalk severing means,

Fig. 5 is a detail sectional view through the bearings for the shaft or axle on which the supporting wheels of the machine are mounted.

Referring more especially to the draw-.,.

with forwardly extending shafts 2, and connected to a transverse bar 3 of saidframe, by'ineans of the links 1, is a suitable swingle tree'5, to which a draft animal (which is designed to be hitched between the shafts) may be connected. Journaled in bearings 6 (which are fastened by bolts 7 to the under part of the frame centrally) is an axle or shaft 8. Rotatable with the axle are suitable supporting wheels 9, which are arranged between the longitudinally extending bars 10 of said frame. Secured at' 11 on a transverse bar 12, of the frame is the support 13' of an operatorsseat14. Supported upon the frame 1 is a segment rack 15, and pivoted thereto, as at 16, is a lever 17, which is provided with a hand grip controlled dog 18 to cooperate with. the teeth of said rack 15, to hold the lever in various adjusted positions. Pivoted at 19 to the leverj 17 is a suitable I link or connecting bar 20.

Fastened at 21 to the underside of the frame, at the rear of the axle, on both sides ofthe frame, arevbrackets 22. upon pivots 23, at the extremities of said brackets, are levers 24, the upper ends of which are connected by the transverse rod 25 ,to which the link or bar 20 is pivotally connected. The lower ends of the levers 24 are integrally connected by the transverse Mounted bar 26, which is provided with laterally eX- tending cutting or severing knives 27, the cutting. edges 28 of which face forwardly. These cutting knives, in addition to extending laterally, eXtend angularly and slightly forwardly, so as to cause a shearing action, whereby the stalks may be severed more efficiently. By imparting backward and forwardmovements to the lever. 17,, the levers 24 may be oscillated, whereby oscillatory chopping and shearing strokes may be 1mparted to the knives to sever the stalks ad jaceht their bases.

Mounted in bearings on'the sides of the frame, near the rear thereof, and in the bearings 29 of the braces 30, are vertical shafts 31, provided on their upper ends a with reels 32. By virtue of the collars 33, which are secured upon the shafts 31, above and below the frame, axial movement of said shafts are'prevented. By virtue ofthe reels 32 "(which constantly rotate as the machine moves forward) the stalks are thrown upon suitable racks. Mounted upon the shafts 31, and rotatable therewith, are bev-v eled gears 34, Arranged-jh bearingsaig theiframe l, at the rear thereof, is atransverse shaft 36, the opposite endsg'ofiiwhichz are provided with beveled gears 37, which mesh; with ,fth'e;v beveled, gears 34;; so?! thatzwhen the shaft 36 is rotated, the shafts 31 and their reels 32 are in turn rotated? Mounted" upon and movable with the shaft 36.isa sprocket 138." In bearings 39 of the frame 1 is a' shaft 40lprovidedlwith a sprocket 4l'and agear 42, which. meshes with the gear 43 of the axle 8. A'suitable sprocket chain 44 en-} I gages about'the sprockets 38' and 41, where-f by revoluble movements, through'the medium .of'the gears 42 and 43, ,may be imparted'to the shafts 36'and'in' turn to the" shafts 31. Projecting rearwardly and up' Wardlyfronrthe rear of the frame are b'rack-' ets45 havinggbearings 46, and extending? from the sides of the bearings and inwardly toward each other arefarm's 47 ,inifbearingsl 48' of which, a "crank shaft 49. l is mounted; The oppositeends'of the crank shaft '49 have? beveled gears "50, and mounted in the-bearings 46"are the shafts 51 of the racks',"which' are designed for receivingithe stalksfas they' areisevered. Suitable beveled gears 52 are fas't' upon the shafts 5 1 ofth'e racks, mesh with the beveled gears 50, whereby, as ,the crank shaft is rocked in one direction or the other, the racks are inturn rocked, so that the 'stalksmay'jbe dumped to one side of the machine. A suitable segment, rack- 53*is mounted upon the forwardpartof the frame l, an'd' pivotedlthereto, as at 54, is a lever 55; Thelever 55 is provi'ded with a hand gripped controlled dog 56, to cooperate with 'the teeth 57 of the rack 53. A suitable rod or link. 58 islconnected to the crankofthe shaft .49, andinturn to the lever-'55, where;

by, when the lever 5'5is oscillated Yin onefldij rection or the other, an oscillatory moves mentzmayl be imparted to the shaft 49,-. so, that the corn'stalk supporting racks may in turn be dumped. The stalk receiving racks consistof' the arms 59, which extend down; wardly, partially "rearwardly and, slightly outwardly and terminate in elongated out-f, Wardly extending curve1d parts 60, upon; which i the; stalks, as, they are severed, are

' thrown by the arms of the revolvin g reels;32;

Secured to the; rear part ofthe lffiame 11in any suitable manner, "and extending rar-; wardly,fjis a V-T'shaped auxiliary frame-61, provided with an extension- 62'. An "arch;
